What is SolCold’s Cooling Technology?
SolCold is developing a unique, next-gen passive cooling coating that’s no thicker than a business card. This innovative material cools itself below the surrounding temperature just by being exposed to sunlight. Once applied to any outdoor surface, the sun’s radiation triggers a reaction in the coating. This reaction converts the heat accumulated in the object into radiation, which is then emitted through a process called “anti-Stokes fluorescence.” Think of it as a thin layer of ice that gets thicker and cooler as the sun gets stronger. It’s simple, sustainable, and powered entirely by sunlight—no electricity needed.

How Does It Work?
At first glance, SolCold’s product might look like just a simple film, but it’s actually a high-tech marvel. The cooling effect comes from combining three powerful mechanisms in one product:
- Reflecting 98.5% of solar radiation
- Converting heat into visible light
- Releasing heat through radiative cooling
By reflecting most of the sun’s radiation and converting the absorbed heat into harmless light, the coating releases this energy back into the atmosphere—without any fuel, electricity, or emissions. It’s a clever way to harness the sun’s power to cool rather than heat.
SolCold’s Mission and Vision
Founded in 2016, SolCold is a world leader in outdoor cooling coatings research and development. Their mission? To simplify and revolutionize natural, sun-driven cooling using advanced coatings, materials, and solutions. They believe the sun, which is our planet’s main source of heat, can also be part of the solution to global warming. The vision is clear: a future where sustainable cities and industries widely adopt these coatings, drastically reducing dependence on electricity for outdoor cooling.
What SolCold Does
Simply put, SolCold makes the sun cool. Their innovative coating reflects heat, converts it into harmless light, and releases it back into the atmosphere—all without electricity or emissions. This technology reduces temperatures below shade under intense sun on any outdoor surface. It cuts energy costs and dependence on air conditioning, easing the strain on power grids. Plus, it helps mitigate urban heat island effects, improves comfort, and lowers carbon emissions. It’s a win-win for both people and the planet.
Project Impact and Sustainable Development Goals (SDGs)
- SDG 7: Affordable and Clean Energy – by reducing electricity demand for cooling
- SDG 11: Sustainable Cities and Communities – by mitigating urban heat island effects
- SDG 12: Responsible Consumption and Production – through energy savings and emissions reduction
- SDG 13: Climate Action – by cutting CO2 emissions and promoting sustainable cooling
- SDG 9: Industry, Innovation, and Infrastructure – via cutting-edge cooling technology
Looking Ahead
SolCold continues to optimize its technology, aiming to replace conventional electrically-powered cooling solutions. With over 40 active installations and a growing customer base, the company is on track to transform how outdoor cooling is approached worldwide. As global temperatures rise and energy demands soar, this solar-powered cooling coating offers a promising, eco-friendly alternative that’s simple, effective, and ready for a hotter world.
